@This invention relates to a pocket pyrophoric lighter, of the type inwhich the operation of an actuating member brings -about, in successionthe `opening of the cover normally fitting closely over the inflammablewick of the lighter, and rotation of the friction wheel co-acting with apyrophorous body to produce the igniting spark, and consists`essentially in so mounting the said I `cover 'and coupling the samewith the moving parts of the actuating mechanism that, in opening, thecover is rst moved axially with respect to the position of the wick inthe lighter and then laterally and outwards. In this manner, as comparedwith the known types of pyrophoric lighter with merely pivoted cover,the result is achieved `that when the cover is closed the'extinguishertstightly over the end of the wick holder or tube, while when the coveris open the whole of the space above the ame is free and untrammeled. l.l

, In accordance with the invention the cover is mounted on a verticalrod which is guided, by means of a guide pin, in a groove in a sleeve,and coupled with the actuating member by a lever arrangement which liftsit out of the sleeve, so

thatit is first lifted clear of the wick and 'then swung outwardsthrough an angle of about 90. A form of construction of lighteraccording to the invention is shown, on a magnified scale, by way ofexample, in the accompanying drawing, in

which:

Fig. 1 shows the lighter according to the invention in side elevation,in lthe closed condition with the side wall broken away to disclose theactuating mechanism'. f Fig. 2 shows Vthe same in plan view. Fig. 3shows the same lighter in the open condition, as after operation;` againin side elevation with the near side wall for the' greater part brokenaway. w

Fig.v4 is a plan view of ,the open lighter.

Referring to the.drawing, in which like parts tionconsists, in a knownmanner, of a housing or casing part I in "the interior of which isstowed l the `fuel tank 2 which is generally lled with wadding or thelike, and from which the wick 3 extends loosely out of a small conicalextension 4. The spring-loaded stick of pyrophorous material 5 is guidedin a tubular holder extending from the bottom to the top of the fueltank, and bears against the friction wheel 6 mounted on top of the tank.The side walls 1, 11 of the casing Iextend beyond theend of the wick,and are provided with air admission apertures 8, and thus serve toprotect the flame from wind. Adjacent the fuel tank 2 and extendingalong the side wall of the casing there is disposed a round section tubeII) having at the lower end a slot I)` which is rst 5 straight and then,further up, of helical shape. Into this tube there is `inserted a roundsection rod I2 which is provided at the lower end on each side with aguide pin II, and to the upper end of Vwhich there is secured the coverI3 ofA the 10 lighter, the said pins II being adapted to engage in theslot 9 in the tube III. On the under side of the cover I3 there issecured the extinguisher I44 which is soA dimensioned that, when thecover is in the closed condition, the extinguisher not 15 only reachesdown to the top of the tank 2 but also fits closely against the conicalsurface of the extension 4 on this tank. f

In place of a front wall to the casing there is athumb piece 23 which ispivoted at the lower-A m most point lli` between the two casing sidewalls 1, 1'1, and which is stressedby a spring I5 tending to force itoutwards. The upper end of the thumb piece 23 is lbent over inwards atan angle and provided on either side with a pin I8. These pins I8 u'wardly extending rack 25 which meshes Iwith a pinion 24 .coupled forrotation with the friction wheels. g 35 The mode of operation of thedescribed pyrol phoric lighter is as follows: When the cover I3 isclosed (that is to say when the lighter is'in the inoperative condition)the thumb piece `23 juts out somewhat beyond the'icontour of the lighter(see Fig. 1), the vertical rod I2 on which the cover I3 is mounted is inthe completely lowered l position, and the pins I I are at the bottom ofthe slot 9. I'o operate the lighter the thumb piece 23 is pressedinwards (Fig..2) against the action of 45 Y the spring I6. 'I'hrough theintermediary' of the pin I8 the lever 20 is thereby tilted so that its.other end movesupwards. This movement is imy parted tothe link22 whichbegins by lifting the rod I2 and with itthe cover I3, and that as long50 as the pin I I on the rod I2 travels inthe vstraight 'portionof theslots 9. As soon as the stud I I rengages in the helical portion of theslot 9 the rod I2 and with it the cover I3 becomes rotated through j(Fig.` 4). Previously, namely at the u beginning o: th movement of thethumb piece Il, the rack It on the thumb piece engages in i the pinionIl, rotating this latter and with it the friction wheel l, with theresult .that sparks are generated which igniteA the uncovered wick. Aslong as the thumb piece Il remains in the pressed-in position the coverI3 remains open When the thumb piece 28 is released it is returned bythe spring It into its initial position, all the other parts vof ,themechanism being thereby also restored into theiroriginal positions.

I claim:

1. In a pyrophoric lighter having an innamrnable wick and a, pyrophorousbody, a over enclosing said inflammable wick in the closed position ofthe lighter, `a. friction wheel bearing against said pyrophorous body, amovable actuating member and means connected with said member, saidcover and said friction wheel and operable upon the actuation of saidmember to first move said cover axially in respect to the posi- -tlon ofthe wick ln the lighter, then move said cover laterally outwardsto itsopen position and then rotate said friction wheel to cause theproduction -of an igniting spark.

2. In a pyrophoric lighter having aninilammable wick and a pyrophorousbody, a cover enclosing said inflammable wick inl the closed position ofthe lighter, a friction wheel bearing against said pyrophorous body, amovable actuatingl member, a rod connected with said cover, a
